It's probably okay to begin by deleting the telephone numbers that use exchange names:
KLondike 5-1234, for example

I'm not sure if I'm an anomaly or what, but friendship with clients seems like a very natural result of this kind of work.  If you show up and bring any of your human self to bear in the moment, real connections do happen.  Sometimes you find you have common interests.  Sometimes you just get to know each other over repeated sessions.  There are any number of client/provider situations where people make friends and think nothing of it.  Personal trainers, yoga instructors, hair stylists.  An escort is a more intimate relationship than any of those, so it only stands to reason.
Yes, boundaries are always important.  Most of us juggle varying degrees of complicated lives.  And we can't always be available to everyone all the time.  I've been lucky that pretty much everyone I've met so far has intuitively understood that. 
 
On the question of answered texts, I think what you're observing is not unique to escorts and their clients.  This is an issue with humans who text.  
As a general rule, do not presume to know why a person has left you on read.  You literally have no idea what someone's life might be at any given moment.  Maybe they're driving.   Maybe they opened your text by accident.   Maybe they're about to go into surgery.  And don't presume to know why someone's not looking at your text but their chat light is green.  Maybe they're texting their grandmother on her death bed.  Maybe they're late to an event and texting for directions.  Maybe they just don't have time for you in that moment.  None of this is inconsistent with friendship.  None of this is inconsistent with checking in on you at later time.  You need to be careful not to confuse the access that comes with friendship with 24/7 availability.

I’m curious about relationships between clients and their regular providers. Do you often chat out of “business” hours?
Do you do any other non sexual activities together? (A fine dinning before going to bed is not included here. I think it’s a kind of foreplay. )
My story. I meet this escort around every two or three weeks if he is in town. During our meeting, talks and interactions have always been good. 
I sometimes try to talk with him by WhatsApp. My messages are always replied but long time delay although it shows he is online. Of course it’s a polite way to say “shut up”. It makes sense no one is obliged to “work” over time. So I don’t contact him unless to schedule meeting time. Confusingly, he sometimes also reaches me out asking how you are doing or have a nice weekend. When I reply there is always another longtime silence. I guess maybe all his regular clients received same message at that time. 
Before I ask him directly someday or never, I’d like to hear your experience. 

Being unable to read the written portion of reviews isn’t tied to membership level, it’s based on your location.
And yes, I completely agree most clients don’t bother doing much due diligence.

you can see the full text of the review by using a VPN set outside of USA.

I don't look at other client profiles that often, but once it a while i look at the profile of a client who has left a review of a provider I'm interested in.  It helps me better understand whether the review is relevant to my likely experience with the provider.  

Yes I am aware of all this :). I'm asking because I have seen him repeatedly at parties ONLY bottoming, his grindr profile only lists bottom and have seen him several times on sniffies posting as a bottom cumdump. I've fucked him in one of these so I have no issues with that haha he's got a hot ass, but I've definitely been before with escorts who say they Top but the vibe was really that they're a bottom with a trimmix prescription. 

Just saw him in DC. Massage was relaxing, mostly light pressure. He’s a gorgeous man with an incredible body and I’ll be seeing him again.
